## Compiling
By default, the Intel compiler suite is installed, but not added to the PATH variable on the new julia login nodes. This is readily done by executing
`source /usr/local/etc/intel_mpi.sh`
`source /usr/local/etc/intel_mpi.sh`. For ALF you can chose the Intel enviroment (instead of SuperMUC or Jurece ...) and it should work just fine.
On virtual machines within openstack there is one issue:
Apparently the Intel compiler option -xHost (automated architecture dependent vectorization) can cause segmentation faults, at least within ALF. Possible alternatives are -axCORE-AVX2 (vectorization upto AVX2 [ymm-register]) and -axCORE-AVX512 (using the 512 [zmm-]register) both work fine, to the best of our knowledge.
